Viral, if the downlaod doesnt work try this here: Its free and you can use it online, you dont need to download somthing. Its im my opinion verry good for what it is, better than paint.
an example: the "outlines" areent there, I used the blur-tool
there are a lot of usefull tools; brush-tool, symetry-tool, blur-tool,...
and the best: you even can draw on different layers!
its a verry usefull program my sister found last week. try it.
